Microstructural Origin of Nonmonotonic Piezoresistivity in Polymer Nanocomposites

open access: yesAdvanced Science, EarlyView.
When polymer nanocomposites are subjected to tensile loading, the electrical resistance‐strain relationship may be nonmonotonic, hampering the use of these materials in real‐world applications. This challenge is addressed through the collaborative use of physical experimentation and computer simulations, establishing the inter‐nanotube junction ...

Plasma Metabolic Profile with Machine Learning Reveals Distinct Diagnostic and Biological Signatures for Pathologic Myopia

open access: yesAdvanced Science, EarlyView.
Plasma metabolic detection combined with machine learning offers a precise (area under the curve of 0.874) and high‐throughput (<30 s) diagnosis for pathologic myopia (serious myopic macular degeneration). The biomarkers indicate the pathologic myopia‐associated systemic metabolic reprogramming, which exhibits specificity for myopic macular ...

The nose and tongue as chemical detectors

open access: yes, 2005
Human chemical senses are the gatekeepers of our digestive system. Chemical separation combined with human sensory perception has been used to isolate and identify a natural non-steroidal anti-inflammatory compound in olive oil.

Unlocking the Interaction Mechanism of CNTs and C‐S‐H on Enhancing Elastic and Viscoelastic Properties of Alite Paste

open access: yesAdvanced Science, EarlyView.
This study explores carbon nanotubes’ (CNTs) role in enhancing alite paste’ elasticity and viscoelasticity. Experimental and simulation results reveal that CNTs weakly influence nucleation but significantly refine C‐S‐H gel structure and calcium hydroxide distribution.
